there seems to be some linux compilations issues, i am discussing this with PMB, officially we have to wait for the
official steam working metamod (1.1

.
In short: We fixed something that is yet to be fixed by the original metamod guys. We compiled it using our own binaries and it runs at our server, but that does not mean it runs on yours. If it does not, i think we have a problem. Perhaps we can share the source code with your for metamod so you can compile it yourself?
